python 基于windows环境的ftp功能

描述：

1、基于备份服务器部署的py程序，将需要备份主机目录下的内容下载至备份服务器（服务端和远端都是windows server 2008）

2、py程序部署在windows服务器，后台运行，基于bat脚本启停程序

FTP代码：

  1 class Windows_ftp(object):
  2     '''
  3     FTP类，基于ftplib模块实现
  4     connect: 连接
  5     login: 登陆
  6     DownLoadFile: 下载文件
  7     DownLoadFileTree: 下载指定目录下的所有文件和目录
  8     UpLoadFile: 上传文件
  9     UpLoadFileTree: 上传指定目录下的所有文件和目录
 10     isDir: 判断是否为目录
 11     cwd: 变更目录
 12     quit: 退出
